This is normal and I would not discourage her reactions in any way. She sees you 24/7 and knows that you ar always there for her. She rarely sees Dad so he is exciting and a "treat" to look forward to. Kids often hav this kind of reaction when told they are going to visit their grandparents. Be glad that she looks forward to visiting Dad - far too many kids dread, whine, and cry when they have to visit the other parent.
We have a similar situation. We're the grandparents raising our 5 & 8 yr. old grandchildren. They were removed from their mother (our daughter) by DHS over a year ago, and given to us temporarily. Mothers rights were terminated and we are adopting them. While they lived with Mom they were always so excited to visit us, on the phone and in person. They could hardly wait to visit us, even though we live 3 blks. away and see them several times a week. They always had a good time when visiting us and since we weren't the parent raising them, we were the "treat" to visit. Now that they live with us, and are doing well, they see Mom supervised by DHS 2 hrs. per wk. They are very excited to see Mom and talk about it the day of visitation. Between visits they rarely mention her or act like they have a mother.
When they're excited to visit Mom I just go along with it and say, "I hope you have fun at Mom's. Don't forget to tell her about the "A" you got on your spelling test last Friday, trip to the zoo, etc.". It is good for their self esteem and emotional well being to have a good relationship with Mom. Every child should have a good relationship with a Mom and a Dad - even if the parents aren't living together.
Do not feel threatened by your little girls excitement to see Dad. He has a special place in her life that you can fill, and YOU have a special place in her life that Dad can't fill.
